Dear Dr Nautiyal

I Know u r simly testing, otherwise u know each of them..

Whatever little I know about few of these, I m sending u with little hesitation

Virtual world

A virtual world is a computer-based simulated environment intended for its users to inhabit and interact via avatars. This habitation usually is represented in the form of two or three-dimensional graphical representations of humanoids (or other graphical or text-based avatars). Some, but not all, virtual worlds allow for multiple users.

The world being computer-simulated typically appears similar to the real world, with real world rules such as gravity, topography, locomotion, real-time actions, and communication. Communication has, until recently, been in the form of text, but now real-time voice communication using VOIP is available.

Virtual reality

Virtual reality is a technology which allows a user to interact with a computer-simulated environment, be it a real or imagined one. Most current virtual reality environments are primarily visual experiences, displayed either on a computer screen or through special stereoscopic displays, but some simulations include additional sensory information, such as sound through speakers or headphones. Some advanced, haptic systems now include tactile information, generally known as force feedback, in medical and gaming applications. Users can interact with a virtual environment or a virtual artifact (VA) either through the use of standard input devices such as a keyboard and mouse, or through multimodal devices such as a wired glove, the Polhemus boom arm, and omnidirectional treadmill. The simulated environment can be similar to the real world, for example, simulations for pilot or combat training, or it can differ significantly from reality, as in VR games. In practice, it is currently very difficult to create a high-fidelity virtual reality experience, due largely to technical limitations on processing power, image resolution and communication bandwidth. However, those limitations are expected to eventually be overcome as processor, imaging and data communication technologies become more powerful and cost-effective over time

Jaron Lanier

Jaron Lanier (born 1960) is a virtual reality developer. He was a pioneer in, and popularized the term "Virtual Reality" (VR) in the early 1980s ^. At that time, he founded VPL Research, the first company to sell VR products.

Artificial reality

Artificial reality was the term Myron W. Krueger used to describe his interactive immersive environments, based on video recognition techniques, that put a user in full, unencumbered contact with the digital world. He started this work in the late 1960s and is considered to be a key figure in the early innovation of virtual reality. His first book Artificial Reality was published in 1983 and updated in Artificial Reality II in 1991 (both published by Addison-Wesley).

The term is occasionally used in New Age spirituality to describe the reality we are currently

Holodeck

The holodeck is a simulated reality facility located on board starships and starbases in the fictional Star Trek universe. The holodeck was first seen in the pilot episode of Star Trek: The Next Generation, "Encounter at Farpoint". An episode of Star Trek: The Animated Series, "The Practical Joker", had anticipated the idea by portraying a recreation room capable of holographic simulations.

 

Mixed reality

Mixed Reality is the merging of real world and virtual worlds to produce new environments where physical and digital objects can co-exist and interact in real-time. A mix of augmented reality, augmented virtuality and virtual reality. Combining a variety of 3D modelling, tracking, haptic feedback, computer human interface, simulation, rendering and display techniques, mixing realities can be a complex process at the very cutting edge of today’s technology.

Simulated reality

Simulated reality is the idea that reality could be simulated — usually computer-simulated — to a degree indistinguishable from 'true' reality. It could contain conscious minds which may or may not know that they are living inside a simulation. In its strongest form, the "Simulation Hypothesis" claims we actually are living in such a simulation.

This is different from the current, technologically achievable concept of virtual reality. Virtual reality is easily distinguished from the experience of 'true' reality; participants are never in doubt about the nature of what they experience. Simulated reality, by contrast, would be hard or impossible to distinguish from 'true' reality.

 The Matrix

The Matrix is a science fiction/action film written and directed by Larry and Andy Wachowski and starring Keanu Reeves, Laurence Fishburne, Carrie-Anne Moss, Joe Pantoliano and Hugo Weaving. It was first released in the USA on March 31, 1999, and is the first entry in The Matrix series of films, comics, video games and animation.

The film describes a future in which the world is actually the Matrix, a simulated reality created by sentient machines in order to pacify, subdue and make use of the human population as an energy source by growing them and connecting them to the Matrix with cybernetic implants.

I shall feel thankful if some one please explain the meaning of these terms/ names put up by Dr. Arvind Dubey.  Hollywood movies may have made some of the terms familiar but many of us may not be clear about the meaning.  Some of them may have subtle difference and some may not have a universally accepted definition or may have time- evolving definitions.  Another option is to go to net and learn but if some one from the board does it, it will be in perspective.  Besides, it will generate discussion clearing up doubts:

 

Virtual world, Virtual reality, Augmented Reality, Neuromencer, Holodek, Matrix, stereoscopic displays Damien Broderick   Jaron Lanier  Myron Krueger and  artificial reality,  Neal Stephenson's Snow Crash.

I see nothing wrong with the topic.  This is a forum where we also wish to educate ourselves.  Virtual reality can be a very inetresting thing in sci-fi.  As a post- script to my orecious post, I may add that my list of familiar topics didn't include' stereo.." as it's common and also a link was given. Also, it is a spirit without body (being on web e.g.), can we call it a ghost?

Thank you Dr. Nautial but could you see some hidden message in Dr. Dubey's post? It appears as if he has euphemisticaly advised the moderator to come with a topic of wider and general interest.What do you think?
Yes Dr.Jekyll pl tell if you have any thing of that sort on your mind?
Could you suggest any topic?
And where is the man in officiating capacity ie on hot seat and keering mum these days.Yes, I am talking about dear Swapnil.

Sear Arvind Dube ji,

 

I am not.  Only with 2. 

 

But as you know more than many of us (including me) despite your modest statement, have interest in and, I believe, access to,info how abot explaining these terms,  even if there are inperfections, debate will be initiated.  I hope you will take suggestion seriously as you are one of the few who can do it.

Plz come out honestly

Like me how many of u r not well versed with virtual world, Virtual reality, Augmented Reality, Neuromencer, Holodek, Matrix, stereoscopic displays Damien Broderick   Jaron Lanier  Myron Krueger and  artificial reality,  Neal Stephenson's Snow Crash, or else not interested to talk about it.

Thanks DR. Nautial for erudite comments and elaborating VR
further.But why many members whom i adore are silent.Perhaps they are

the successive growth and development will be a complex function of
the inherited genetic qualities and experiences which will programme
the mind of the person as to how (s)he will react to any stimulant or
situation. This means the clones can be people with very different
personalities.

computer (artificial intelligence) who thinks and behaves like the
original one. If an artificial computer with capacities similar to
human brain has to be built today, it may be size of a room. Super
conductors and other such materials may soon change it though (fiction
writer can take liberty here). This virtual clone will have to fed
with all the experiences and instructions which the original has
experienced. It's a different problem that at present there is no way
all the info can be extracted from one's 's brain (brain- mapping,
positron tomography may be useful in very limited manner), and
depending on one's memory for feeding the potential clone (computer)
would have its own hazards of selcetive omissions and additions
(another point which sci- fi writers can exploit). There can be
'mutations' in transferring the info giving a handle to sci- fi writer
to control the story line..

> The climax in a fiction may have a clone behaving against the wish
or expectation of the original. The original always presumed that the
clone would exactly know and act as the original would, but it may not
happen that way. The virtual clone, having had additional experiences
(no emotions) and different set of circumstances and people/ machines,
may have modified or , over written the original programme-
statements of his mind. Sometimes we act randomly. We also don't
always act logically or may be governed by what can be termed gut
feeling (foolhardiness and an act of bravery- outcome deciding the
nomenclature!). So even when the brains of orginal and the clone may
be identical in capabilities, but mind would have qualitative
difference and hence action different.
